摘要
介绍总线通信模块的结构,重点介绍EZ-USB FX2芯片在FIFO模式下的结构配置、基于FPGA的总线协议模块的设计,以及总线协议模块中的FIFO与USB通信的结构设计,并就电平转换和电源管理等问题给出了具体解决方案。该模块具有4个独立的收发通道,具有传输速度快、携带方便等优点。经仿真测试和实际检测结果表明:该模块不仅满足机载设备的通信要求,也满足航空应用环境和可靠性要求。
The structure of bus communication module is discussed.Structure configuration of chip EX-USB FX2 working in the FIFO mode and bus protocol module based on FPGA are introduced in detail.The communication structure design between FIFOs in the bus protocol module and USB is also presented.The sulution of problem such as the level translator and power management is provided.The module has such characteristic as four channels,speediness and portable.Results simulation and actual test indicates that the module is not only fulfill the request of communication among devices on board,but also compliance to avionic application condition and reliability.
